Cover Story: In this work, a sensitivity analysis for the standardized precipitation-evapotranspiration and aridity indexes was carried out using three different PET models, namely the Penman–Monteith model, a temperature-based parametric model, and the Thornthwaite model. The analysis was undertaken in six gauge stations in the California region where long-term drought events have occurred. Having used the Penman–Monteith model as the PET model for estimating the standardized precipitation-evapotranspiration index, our findings highlight the presence of uncertainty in defining the severity of drought, especially for large timescales (12 months to 48 months), and that the PET parametric model is a preferable model to the Thornthwaite model for both the standardized precipitation-evapotranspiration index and the aridity indexes.
